I've encountered an issue while working on my Angular component. Here's the relevant code snippet:
class Test implements ....{
duration:{from:number, to:number}
constructor(){
this.duration.from = "ddd";//set after some calculations
this.duration.to = "ddd";
}
}
When I run this code, it throws an error saying "cannot set property from of undefined".
Can anyone help me figure out what I'm doing wrong here?
Within your code, you have declared a variable called duration and specified its type; however, you have not provided an initial value for it, causing the variable to remain undefined. Instead of assigning properties this.duration.from and this.duration.to, it is recommended to initialize the variable as shown below:
class Example implements ....{
duration:{from:number, to:number}
constructor(){
this.duration = {
from: 1,
to: 2
};
}
}
